Please draw the cooling curve at standard pressure for benzene, C6H6 (MM = 78.01 g/mol). The normal freezing point of benzene is 5.00 oC, and the normal boiling point is 80.2 oC. Calculate the total enthalpyfor the process of converting 35.00 g of benzene vapor at 100.0 oC to solid benzene at -6.00 oC.
Please provide the work too, thanks!

A solution consists of 3.88 g benzene,C6H6 , and 2.45 g toluene
,C6H5CH3. The vapor pressure of pure benzene at 20. °C is 75 mm Hg
and that of toluene at 20.0 °C is 22 mm Hg. Assume that Raoult’s
lawholds for each component of the solution, calculate the mole
fraction of benzene in the vapor. ( molar mass of benzene= 78.0
g/mole and toluene = 92.0 g/mole.)
Answer= 0.87
